/**
 * 核心原理
 * 1)、@EnableRedisHttpSession导入RedisHttpSessionConfiguration配置
 *      1、给容器中添加一个组件
 *          SessionRepository = >>> 【RedisOperationsSessionRepository】=>>> redis操作session session的增删改查封装类
 *      2、SessionRepositoryFilter =>>>Filter  session 存储过滤器每个请求过来都必须经过filter
 *          1、创建的时候,就自动从容器中获取到了SessionRepository
 *          2、原始的request,reponse都被包装SessionRepositoryRequestWrapper，SessionRepositoryReponseWrapper
 *          3、以后获取session， request.getSession();
 *          4、wrapperRequest.getSession(); ===> SessionReponseitory 中取得的
 * 装饰者模式
 * 自动延期,redis中的数据也是有过期时间的
